NWRI contribution ; no. 03-164 Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographic references. "Potential impacts of road salting on the environment have increased by introduction of stormwater management practices. Specific impacts are discussed for four such practices, infiltration facilities, oil and grit separators, stormwater ponds and constructed wetlands. The main concerns about (hazards of) chloride-laden stormwater discharges include contamination of groundwater, leaching out of trace metals, densimetric stratification and poor vertical mixing in ponds, direct and indirect toxic effects, benthic drift and reduced biodiversity. The associated environmental risks need to be reduced by chloride source controls, and prevention of excessive chloride accumulations by appropriate design and operation of stormwater facilities in winter months"--Abstract.
